Wiring in a MOSFET R/R

I am looking at installing a lithium ion battery and my research is saying I should include a MOSFET R/R to control the charging of said battery. The MOSFET R/R kits that I have seen on eBay have only 5 wires and my existing R/R has 6 wires. I am assuming the 6th wire is a voltage sensing as it is acting as a ground for light bulbs per the wiring diagram. Do I tie this 6th wire to the ground? Any help is appreciated.

The brown wire is a sensing wire. Don't use it for anything.

No eBay APP ID and/or Cert ID defined in Kunena configurationNot a MOSFET type, get a SERIES type R/R like a Shindengen SH775. It's superior tech to the FHXXX type shunting Shindengen R/R's. You can find them in ebay for good prices. Just be careful to not buy a counterfet unit. Make sure SH775 is printed on the top fin.

The brown wire is a power wire. In addition to acting as a voltage sensing wire for the reg-rec, the brown wire circuit also usually supplies voltage to other components, such as the horn. If you keep the stock wire harness connector for the reg-rec & splice in a mosfet pigtail-jumper harness to the other half of the connector, you should be able to keep the brown wire routed to that connector where it won't be connected to anything. If you cut off that connector from the wire harness, you'll have to secure & insulate the brown wire terminal.

Nessism has mentioned a Triumph mosfet harness that you can get for pretty cheap. Triumph P/N T2500676.
I would get a mosfet harness, then connect it to the motorcycle's wire harness the same as the stock reg-rec, using a new stock type 6-pin connector. Z1Enterprises.com or CycleTerminal.com. etc.

Thank you for your responses. This is very close to the rectifier I plant to get. Also, I am planning to reuse the same connector to the wiring harness by either getting a new connector from cycle terminal or gingerly punching out the existing terminals and using new terminals.

Just to make sure I get this right. Is the brown wire serving as a positive or a grond to the various bits that it is running out to on the bike (e.g. horn, voltmeter in the dash etc. And should I connect this line to the positive or negative on the rectifier?

Brown is hot when the key is on.

Snip off the brown wire and tape or heatshrink back the end. Put that thing to ground and you are going to be in a world of hurt.

Back in the day Shindengen made a couple series of R/R's that used those sense wires. Honda used a lot of that type, and Kawasaki (obviously). By modern times they are old tech though. Again, the SH775 Series type R/R's are where it's at now since they protect your stator. Polaris used these R/R's on their RZR and Ranger vehicles and you could get a brand new one for about $70 as of a year or so back. Word got out how good they are though and now they are $150+. Sucks. Search on SH775 and you will find tons of info about them. They are the motorcycle forum darlings for bikes that burn stators.

So, in order to keep the horn and light's etc. that were fed or grounded by the brown wire, do I ground it or put it to hot (not necessarily on the r/r)

Repeating what others have said...
the brown wire is positive battery voltage when the ignition switch is on. It is NOT ground. Connecting it to ground will blow fuses. Don't do that.

Leave it unconnected and taped up Or you can leave it in the connector as long as it does not connect to any wire on the mating connector.

I apologize for being so pedantic in my earlier posts. I see what you all are saying and I get it now. That wire isn't providing power, it is merely sensing it. The brown wire is branching off the brown wire that is being fed from a fuse in the fuse block. I thank you all for your help and hope that you have happy holidays and a merry Christmas.
